KVP 17-4 SS Pistol Caliber Carbine XP Spring KVP 17-4 SS AR-15 Reduced Power Trigger Spring Kit KVP 17-4 SS Pistol Caliber Carbine XP Spring

Pistol caliber carbines such as 9mm, .40 S&W, .45 ACP, and 10mm are a blast to shoot but can be tough on AR-15's internal components. Without a properly tuned blowback system, you run the risk of being overly destructive on internal lower parts. Running a blowback AR15 with a suppressor can further increase the risk for damage. In addition to a properly weighted buffer, the KVP Extra Power recoil spring is a must! The KVP XP 17-4 SS spring offers increase pre-load over standard springs. The additional preload helps keep Blowback operated systems closed longer.

Mil-spec AR-15 triggers typically have an 8 to 9 pound trigger pull with factory springs. Utilizing the KVP Reduced Power Spring Kit should achieve a trigger pull reduction of 2 to 4 pounds. A 5 to 6 pound trigger pull is typical after installation of the KVP Reduced Power Spring Kit.

Upgrade your standard, carbon steel recoil spring, to a KVP 17-4 Stainless steel recoil spring. Carbon steel springs have the potential to rust if not properly cared for. KVP passivate finish's all our 17-4 Stainless Steel CAR recoil springs to protect them in even the harshest of environments. In addition, our AR-15 Carbine Spring has a cycle life rating over 10,000. If you demand the best, the KVP Carbine Spring will deliver.
